| 2 | Application | ULP-AMI | Ultra Low Power Active Medical Implant communication systems (ULP-AMI) This RIR covers systems specifically designed for the purpose of providing non-voice digital communications between active medical implants and/or body-worn devices and other associated peripherals used for transferring non-time critical individual patient-related physiological information. |
| 3 | Frequency band | 405 - 406 MHz | - |
| 4 | Channelling | 25 kHz Individual transmitters may combine adjacent 25 kHz channels for increased bandwidth up to 100 kHz. | Techniques to access spectrum and mitigate interference that provide at least equivalent performance to the techniques described in harmonised standards adopted under Directive 2014/53/EU must be used. Alternatively a duty cycle limit of 0,1 % may also be used. |
| 5 | Modulation / Occupied bandwidth | - | - |
| 6 | Direction / Separation | - | - |
| 7 | Transmit power / Power density | Max. 0.25 uW e.r.p. for systems using LP/LDC. Max. 25 uW e.r.p. for systems using LBT/AFA. | LP = Low Power. LDC = Low Duty Cycle. AFA = Adaptive Frequency Agility. LBT= Listen Before Talk. Refer to clause 10 of EN 302 537 for functions and limits of MEDS with LBT/AFA. |
| 8 | Channel access and occupation rules | Duty Cycle max. 0.1% for 0.25 uW e.r.p. power limit. LBT/AFA for 25 uW e.r.p. power limit. | Techniques to access spectrum and mitigate interference that provide at least equivalent performance to the techniques described in harmonised standards adopted under Directive 2014/53/EU must be used. Alternatively a duty cycle limit of 0,1 % may also be used. |
| 9 | Authorisation regime | Switzerland: License exempt. Liechtenstein: General authorisation. | Operation on NIB / NPB. (Non interference basis / non protection basis). |
